Yeah you can get burned out real easy. If you jump right in and try to go to the top getting all the popular fish or most sought out fish and spend bunches of money on it in the process, only to give you a sense of belonging or achievement then you will not last long in the hobby.
If fishkeeping is something you are passionate about and like fish for several reasons then you will last longer. If you only got in to fishkeeping cause your Friends were, or you bought only the fish that were aggressive, you won't last long. I can appreciate all types of fish, I can keep aggressive, passive, colorful, invertebrate, native, and planted tanks. I even like breeding tiny organisms like scuds and daphnia. I like breeding worms too. I have felt burned out at times but now I just keep things simple with a few small tanks. I only have a 20 and 29 gallon now. Both are planted, in the 29 I keep tropical fish (Angelfish, 2 ram cichlids, few tetras and ottos), and the 20 gallon is a few small native fish (darters, pygmy sunfish). I really enjoy the tanks even though many people would not consider them MONSTER tanks, I don't really care. I am not here to impress anyone, and never got into fish to impress anyone either. It's all about your enjoyment, not trying to fit in and get monster tanks and monster fish cause others will respect your more or something.
Anyway, taking time off is a good thing, it allows you to reflect on things and re evaluate yourself and your goals. If you come back into fishkeeping come back with goals that are gonna keep you happy in the long term and for your enjoyment. And keep things simple.
